inflection f(x)=x^3-3x^2-45x+5

Solution

inflection points

f (x) = x^{3} - 3 x^{2} - 45 x + 5

Solution

(1, - 42)

Solution steps

f^{''} (x) = 6 x - 6

Find intervals:

Concave Downward

: - \infty < x < 1,

Concave Upward

: 1 < x < \infty

Plug

x = 1

into

x^{3} - 3 x^{2} - 45 x + 5 : - 42

(1, - 42)

Popular Examples

parity f(x)=(x^2-x)/(x^2+1)parity

f (x) = \frac{x ^{2} - x}{x ^{2} + 1}

range of e^x-3 range

e^{x} - 3

domain of sqrt(4-2x)domain

4 - 2 x

domain of f(x)= 1/(sqrt(2x^2-7x+3))domain

f (x) = \frac{1}{2 x ^{2} - 7 x + 3}

critical f(x)=4x^6-6x^4 critical points

f (x) = 4 x^{6} - 6 x^{4}
